What do you have controling water flow/circulation in your tank?

Was wondering what people here have for their water flow/circulation in their tank? Also what is best to use for flow/circulation in a 150 gal tank and the placement of the powerheads? I have a MP40 on the right side of my tank and on the left I have a Korilia 4 due to a damaged driver for my other MP40 so had to take it down and put the K4. I feel like that is not enough circulation in the tank. Any advice on that? Also my sand bed has green algae building up on it, Im guessing its because of that since My MH bulbs are only 1 1/2 months old and have TLF media with GFO in it controling the phosphates along with some chaeto and Mangroves. Corals are growing fine, all my parameters are where they should be. Please post pics if possible.

thats alot of circulation,well compared to mine. does it disturb ur corals? and would thst amount of circulation keep my sand bed algea free?
